Any help described

Answer 1

Option 1: You can try:

 sudo apt-get upgrade 

The upgrade option attempts to resolve all dependencies in installed packages. Often this is enough to solve broken packages.

Option 2 If your package was installed from the "deb" file, and not from the repositories, it may turn out that the new one you are trying to install causes a conflict, and as a result, you must first uninstall the previous version of the package. You can do this from the Software Center or directly with:

 sudo apt-get remove libapache2-mod-wsgi sudo apt-get clean sudo apt-get autoclean 

then

 sudo apt-get update sudo apt-get install libapache2-mod-wsgi 

Hope this helps!

Answer 2

I also have the same problem for sudo apt-get install npm.

Tried to

 sudo apt-get remove npm sudo apt-get remove nodejs 

then

 sudo apt-get clean sudo apt-get autoclean 

then sudo apt-get install nodejs sudo apt-get install npm

decided for me!

Answer 3

This will work for virtual errors errorcode1, and also E is unable to find package problems

  sudo apt-get update sudo apt-get install python-software-properties sudo apt-get install apt-file sudo apt-file update sudo apt-get install software-properties-common sudo apt-get install <your filename> 

Answer 4

My problem was that I was doing a silent installation using the -qq flags. Disabling them showed a dependency problem for me.
